SOLDERING-TOOL.

SPECIFICATION forming part of Letters Patent No. 223,945, dated January 27, 1880.

' Application filed Septembrr 30, 1879.

To. all whom it may concern Be it known that I, DELOSSPALM'ER, of Chicago, in the county of (Jook andStatc of Illinois, have invented a new and useful Im- 5 provementin Soldering-Tools, of which the following is a specification, reference being had to the accompanying drawings.

The nature of my invention relates to devices for soldering tin cans; and it is my ob- Io ject to provide a tool in which the soldering metal can be melted, and by means of which it can be supplied to the several cans in a fused condition and in uniform quantities, this device being particularlyintended to be I 5 used in combination with the apparatus for soldering tin cans which I have described in the specification forming part of my separate application.

My invention consists of an iron funnel hav- 2o ing a handle to its mouth end, and being arranged in its bottom end with a double valve operated from a bell-crank arm which is pivoted to the side of the handle, Each depression of this arm will change the position of the 2 5 valves for discharging a certain amount of soldering metal, which is melted in said funnel by a gas-jet and air-blast attached to the side of the same.

In the drawings, Figure 1 represents an elevation of the soldering-tool; Fig. 2, a longitudinal vertical section of the same; Fig. 3, a section on line a; w, and Fig. 4 a section on line y y, of Fig. 2.

Like letters in the several figtyres of the 3 drawings designate like parts.

A denotes a slender cast-iron funnel, having flange a to its upper edge for securing to it the wooden handleB by an eyebolt, G, and screwnut c. The lower end of this handle B is in- 0 closed in a thimble, D, having lugs d, between which is pivoted the apex of a bell-crank, E. The longer arm of this bell-crank E stands about parallel with the handle B, and is held off by a leaf-spring, e, which extends from the bell-crank has a bifurcated end and is pivotally connected with valve-rod F.

The lower end offunnelA is cast solid, and

is bored and counterbored for forming a cylindrical chamber, 9, with an upward valve-seat,

and the lower end of this chaniberis internally screw-threaded for coupling therewith a nipple-shaped plug, H, the upper end of which being screw-threaded. This plug H is bored out centrally from its top to form a socket, h, therein, which is countersunk on its upper end I for forming a valve'seat, and a small vent, 1', is drilled through the remaining wall to the bottom of said socket at an angle of about forty-five degrees therewith.

The lower extremity of rod F carries two conical valves, f and f,one of which is to lit the seat in the upper end of chamber g and the other one to lit the seat in plug H, and both these valves are placed such a distance 6 5 apart that only one at a time can closeupon its seat, while the other one is held. in suspense. The action of spring 6 against bellcrank arm E will press the lower valve, f, upon its seat, and by pulling said arm E toward the handle B so as to compress said spring 6 the valve f will be raised off its seat and the valve f will be closed.

With the above arrangement each operation on the valves will discharge through vent i a determined measure of fused metal equal to the capacity of chamber g.

Opposite to handle B the funnel A has a semicircular groove, which is formed longitudinally in its wall, and extends from near its top to the valve-chamber portion of said funnel. Into the upper half of this groove is seecured one shank of an elbow-shaped pipe, J. A smaller pipe, j, which is also elbow-shaped, pierces the pipe J at its curved point, and ex- 8 5 tends inside thereof to near its end. This pipe j is to be connected by a hose or flexible pipe with a gas-supply pipe, and the larger pipe J is to furnish a sufficient currentof atmospheric air to the ejected gas, either by natural draft 0 or by flexibly connecting it with a blower. The air and gas thus thoroughly mixed will produce a long smokeless. flame for heating the funnel.

The lower half of the funnel A is covered by 5 asheet-metal sleeve, L, having a semi-cylindrical bulge, I, which covers the groove in the funnel-wall and forms a round flue therewith, and exterior-1y its whole length this bulge Z is perforated with a row of small holes, and with IOO a larger opening in its bottom end, for providing a free outlet for the products of combustion of the burning gases blown through this flue.

By means of the eye (Jto the end of its handle the tool is to be suspended to the end of a cord or chain passed over pulleys, and having a counterweight to its opposite end, that the tool may be raised and lowered with ease, and that it will he hoisted out of the way when not in use.

After filling the funnel A with soldering metal and turning on and igniting the gasjet, said metal will melt and will be kept at the filsingpoint, when the operator, by taking hold of the handle B for directing the tool, with every compression upon the hell-crank arm E, can discharge a uniform amount of metal into a can to be soldered.

In locations where gas cannot be had the funnel may be heated by a different device for fusing the metal therein.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. In a tool for melting solder and dropping it in regular quantities, the combination, with the funnel A, of the air and gas pipes J j, attached to the side of such funnel, the gas-pipe terminating within the end of the air pipe, substantially as and for the purposes set forth.

.2. In a tool for melting solder and dropping it in regular quantities, the combination, with the funnel A, of the gas and air pipes Jj, terminating one within the other at the side of the funnel, and the perforated sleeve L, placed around such funnel and over the end of the gas and air pipes, for the purpose of heating the funnel, substantially as described an shown.

3. The funnel A, having handle B, bellcra-nk E, spring 0, rod F, with valves ff, chamber g, and socketed plug H, with vent i, the same being constructed and arranged to operate substantially as and for the purpose set forth.

4. In combination with the funnel A, having handle B, bell-crank E, spring 6, rod F, with valves ff, chamber y, and plug H, with socket h and vent i, the gas and air pipes j J and collar L, with perforated bulge l, the whole of which being constructed and arranged to operate substantially as and for the purpose described and shown.
